User authentication

slide-7
SLIDE 7

Identification of products

  • The user takes the picture of the

barcode.

  • The picture is sent to the server.
  • The server sends the information about

the product.

Product removal features

  • Scenario: the user wants to remove “coca cola”, because he has not enough

money to buy it.

Server side

slide-15
SLIDE 15

Communication with the board

  • UDP channel
  • stateless communication:

each request is independent from the others

Code recognition and processing

Types of codes:

  • 1D codes: for the products
  • 2D codes: for customers

Steps:

  • receive image
  • Zebra-crossing library to detect code
  • lookup in the database
  • provide result back to the board
